Title: Ventilation fan for duct
Inventor: TSUKITARI YUJI
IPC: F24F7/10
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To enable an ornamental cover to be positively fixed even if the ornamental cover is slightly slanted to advance in a forward direction during fixing of the ornamental cover and also even after fixing of the ornamental cover to enable the fixed state of the ornamental cover to be positively maintained. SOLUTION: This ventilation fan is constructed such that twisted coil springs 24 having an arm section 26 are arranged at both sides of a ring section 25, the arm section 26 of the spring 24 is engaged with a spring hook part 22 in a main body 11 to apply a resilient force to cause the arm section 26 to be expanded, a hook part 30 of the ornamental cover 27 is engaged with the ring part 25 of the spring 24, the ornamental cover 27 is pulled up by the expanding resilient force of the arm section 26 of the spring 24 and further fixed to the lower part of the main body 11. In this case, the hook part 30 of the ornamental cover 27 is displaced from the spring hook part 22 in an engaging advancing direction with the spring 24, resulting in that the spring 24 is flexed to cause the ring section 25 to be press contacted with the deep part of the hook part 30.

Title: Apparatus for quenching ball screw shaft
Inventor: HAGI TATSUYA
IPC: C21D9/28
Filed: 1991-01-17
Abstract: PURPOSE:To make steel ball rolling face in a ball screw shaft perfectly quenched with high energy beam by flowing cooling material into a through-hole in the ball screw shaft. CONSTITUTION:By circulating cooling water 19 or beforehand filling up liquefied nitrogen 18 into the ball screw shaft 12 forming the through-hole 12a in its axial direction, through which the cooling water 19 or the liquefied nitrogen 18 passes, the ball screw shaft is beforehand uniformly cooled. In this condition, the ball screw shaft 12 is rotated, and laser beam 28 irradiates the steel ball rolling face 10 in the ball screw shaft 12 and the quenching is executed. As the heat accumulated in the ball screw shaft 12 is absorbed into the cooling water 19 or the liquefied nitrogen 18 during working, the accumulated heat in the ball screw shaft does not exist.

Title: Spike protrudible tire
Inventor: NAKAMURA KINYA
IPC: B60C11/16
Filed: 1981-01-14
Abstract: PURPOSE:To have a tire furnished with spikes which can be protruded and retracted according to necessity by means of application of pneumatic pressure. CONSTITUTION:While spikes 4 are not necessary the compressed air is put in an air bag 5 and a receiver plate 3 for a spike 4 is pressed to a rim 2. Thus the spike 4 is retracted. When spikes 4 are necessary the air bags 5.5 are exhausted to allow them to contract and the spike 4 will protrude from the surface of tire 6 owing to the car's weight. Provision of an air container in the car will give protrusion/retraction of spikes with the aid of very simple manipulation.

Title: Memory device
Inventor: SUGIMOTO EIJI
IPC: G11C11/419
Filed: 1980-01-18
Abstract: PURPOSE:To obtain a high-speed and small-area memory circuit, by interposing insulating gate type FETs for precharging and loading between a data line and the output of an inverting amplifier. CONSTITUTION:Although X address input signal I1 is inputted at times T11-T12, precharge signal PR is at [1], so output X address line AX1 of NOR gate GX1 stays at voltage [0]. At time T12, signal PR is at [0] and when signal I1 is at [0], the voltage of line AX1 reaches [1] time lag tc later to select a memory cell. On the other hand, data lines Ka1 and Kb1 are charged to constant characteristic voltage VF in period T11-T12 by short-circuiting the input and output of an inverting amplifier by turning on insulating gate type FETQp1. After period T12, the voltages of the data lines vary with the state of the selected memory cell. Then, the charged voltages of the data lines are automatically set to the point of the highest amplification factor of the inverting amplifier, so that the high-speed detecting circuit whose output varies greatly with even slight variation of the data lines can be obtained.

IPC: G05B19/05
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To generate an event-driven program without paying attention to timing and to decrease the number of steps of a sequence program on the whole. SOLUTION: A user registers an interruption occurrence condition and an interruption number in a link unit (interruption occurrence condition registration part 24 and interruption number registration part 25) in advance. A programmable controller(PC) OS part 11 normally executes a user program stored in a user sequence program memory part 12. The link unit 20 compares data in a link device memory part 22 with the registered interruption occurrence condition by a comparison part 26 at the end of a series of transmitting processes and initiates an interruption to the PCOS part 11 when the contents match each other. The PCOS part 11 having received the interruption temporarily stops the sequence program which is currently executed and executes the interruption program corresponding to the interruption number.

Title: Instrument for measuring vertical landing deviation quantity
Inventor: MURANAKA MASATAKA
IPC: H04N3/16
Filed: 1992-01-14
Abstract: PURPOSE:To shorten measuring time even if a measuring position is changed and also to correctly measure landing deviation quantity by simultaneously displaying two beam spots with low brightness within one section in the vertical direction. CONSTITUTION:A 1 & 12 line cathode-ray driving circuit 52 generates cathode- ray driving pulses (2A-S) by using a horizontal synchronizing signal HP and a control signal outputted from a pulse generating circuit 39 as data. The driving pulse is heated by a flowing current during a high potential period and the driving pulses (A-C) are held so as to discharge an electron during the low potential period. Thus, the electron is discharged during the two-horizontal- scanning period when the respective driving pulses(A-S) of low potential are added from the 19 cathode-rays 2A-2S. During the period when high potential is added, potential which is added to the cathode-rays 2A-2S becomes higher than potential in the periphery of the cathode-rays 2, which is fixed by a bias voltage added to a rear electrode and a beam drawing electrode so that the electron is not discharged from the cathode-rays.

Abstract: PURPOSE:To maintain the rate of change of a field current per one step of the output voltage of a field converter by controlling the firing angle of the converter so that the stepping amount of the output voltage increases in response to the high or low amplitude of the output voltage of the converter. CONSTITUTION:Comparing means 201 outputs a command for increasing or decreasing the firing angle alpha of a field converter FRf in response to the polarity of the deviation when the amplitude of the deviation between the target value signal I* and the actual value signal I exceeds the prescribed value B. Integrating means 202 integrates the output of the means 201 and outputs it as a command value of the firing angle alpha to phase shifting means 202. On the other hand, function generating means 204 converts the firing angle alpha to the amount corresponding to the amount DELTAalpha of variation in the step of the firing angle so as to increase or decrease the amount DELTAE of variation in the stepping amount in response to the magnitude of the output voltage Ed of the field converter FRf, and applies it to the means 202.

Abstract: PURPOSE:To simplify the manufacturing process of a HYB IC by a method wherein a thin film resistor is prepared in such a way that a dumbbell part is not allowed to form on the surface to omit an inconvenient photoresist covering process. CONSTITUTION:The required part of a Ta thin film 5 on an insulated substrate 4 is electrolytically formed an anodic oxide layer 7.
